Aerialist Nik Wallenda pauses during his quarter mile walk over the Little Colorado River Gorge in northeastern Arizona on Sunday, June 23, 2013. The daredevil successfully traversed a tightrope strung 1,500 feet above the chasm near the Grand Canyon in just more than 22 minutes, pausing and crouching twice as winds whipped around him and the cable swayed.
